' 13 Claims. ((1242-65) a This invention relates to paper reelingapparatus and has particular reference to apparatus for winding a web ofpaper in predetermined lengths on suitable spools.

g The main objects of the invention are to provide means forautomatically transferring the web from a full roll to an empty spool;to provide means controlled by the spool and by the length of paper webwound on the roll for effecting operation of the automaticspool-changing mechanism; to provide such automatic mechanism which willoperate efficiently and smoothly without jars or shocks; and, ingeneral, it is the object of this invention to provide improved paper itreeling apparatus.

Other objects and advantages of this invention will be understood byreference to the following specification and accompanying drawings (foursheets) wherein there is illustrated a paper reeling apparatus embodyinga selected form of the invention.

In the drawings- Fig. l is a plan. Fig. 2 is a section on the line 22 ofFig. 1. M Fig. 3 is a view similar to Fig. 2 but showing certain partsin a changed position.

Fig. 4 is a schematic illustration including wiring diagram.

Fig. 5 is a section on the line 5-5 of Fig. 2; and till Fig. 6 is adetail illustration of certain pneumatic mechanism.

Referring now to the drawings, the apparatus illustrated includes a maindrum Ill which is journaled in suitable end frames such asv indicated atht: ii. The drum I may be driven from any suitable source of power, forexample, by means of a power-driven belt I? which extends around apulley it carried by the drum shaft.

A paper feed belt it extends around a suitable roller it carried by asupport it, under the drum iii, over a roller ll journaled in suitablebrackets such as l8 which are carried by the end frames paper machine,calendering. rolls or other apparatus, and to deliver such web to thedrum iii. For maintaining the belt it in properly adjusted relation tothe drum ill, the roll i9 is journaled in brackets such as 2| which aresuspended on pivots 50 such as 22 carried by brackets 28. The brackets23 are mounted on end frame members 24. The arm M is yieldingly urged toswing away from the drum it by means of a weight 25 which is connectedto the arm 2 I through the agency of a suit- 55 able cable 2t. The cable26 extends around a roller 21 which is rotatably supported in a suitablebracket. The roller 20 may also conveniently be rotatahly mounted'inbrackets 28 which may be adjustably mounted in any suitable manner tofacilitate horizontal or other adjustment of 5 the roller.

Empty spools on which the web of paper is to be wound are delivered tothe apparatus on tracks 29 which may conveniently be in the form ofchannel iron members suitably mounted on supl0 porting frame members 38.In Figs. 2 and 5, an empty spool is illustrated on the delivery end ofthe track 29 and is designated S. For preventing the empty spool S fromrolling off the end of the track, an arm 39 provided with an upstandingportion 32, is pivoted on the inside of the track as indicated at 33.The arm M is normally urged to swing upwardly so as to maintain theprojecting portion 32 in the path of the spool shaft, by means of aweighted arm at. Of course it will be understood that tracks like 29 areprovided for each end of the empty spools and that each track end isprovided with the described spool-retaining arm arrangement. At the freeend of the arm ii there is provided an extension 35 which is adapted tobe engaged by an arm presently to be described,

7 for swinging the latch arm 3! downwardly to permit the roll S to rollofl the end of thetrack to such arm. The tracks 29 are preferablyinclined at a slight angle which is suiiicient to cause the rolls tonormally roll toward the delivery end of the track and off the trackwhen the latch ii is disengaged.

Arms such as indicated at 36 are pivoted as at $1 on the inside oi therespective end frames Ii and these arms are adapted to carry an emptyspool received from the tracks 29, to operative position relative to thedrum (shown in Fig. 2) in which the paper web may be wound on the spool.The arms 36 are provided at their free ends with 0 spool-receiving seats38 and the end portions 39 of these arms serve to engage the extendedends of the latch arms 3i to disengage the same as previously explained.The position of the arm 36 lllustrated in Fig. 3 is the lowered orspool-receiving position and the latch at is there shown in itsdisengaged position. By comparison of Figs. 2 and 3, it will beunderstood that the arms 36 are adapted to be swung upwardly on theirpivots 31 to carry the empty spool received by the arms into saidoperative position.

For actuating the arms 36 and other parts which will presently bedescribed, there is provided a pneumatic cylinder ill having a piston 4iand piston rod 42' adapted to be reciprocated in accordance with theadmission of compressed air into one end of the cylinder and release ofair from the other end. The piston rod 42 is provided at its free endwith a rack bar 43, which is suitably supported for reciprocation on aroller bearing 44. The rack bar meshes with a gear 45, which is securedto a shaft 45. the latter being journaled in suitable bearing standssuch as 41 and 41 (see Figs. 2 and The shaft 45 also carries gears suchas 43 located adjacent the outsidelof the respective supporting framemembers 24.-' The gears 45 and 49 are of like construction and in Fig. 2are concentrically disposed and hence the gear 45 is directly in back ofthe gear 48. The gears 45 mesh respectively with gear segments such as49 which are pivotally mounted as indicated at 50, on respective sideframe members 24. It will be evident that by reciprocating the rack 43,the gear segment 49 will be oscillated. Extending from the hub of thegear segment 49 is an arm 5| to the free end of which there is pivotallyconnected one end of a link 52. The lower or opposite end of the link 52is provided with an elongated slot 53 which receives a pin 54 pro--nected to the arm 36.

When the rack bar 43 is moved outwardly, i. e., to the right in Fig. 2,the gear segment 49 will be turned in a clockwise direction with theresult that the arm 36 will be lowered. It will be evident that theweight of the arm 36 causesthe same to swing downwardly when permittedto do so by downward movement of the link52. It will also be evidentthat when the rack bar 43 is moved toward the left in Fig. 2, thesegment gear 49 will be turned in a counter-clockwise direction, therebymoving the link 52 upwardly. Initial upward movement of the link 52 willnot actuate the arm 35 inasmuch as the slot 53 provides for lost motionin the connection between the link 52 and arm 55. However, when thelower end of the slot 53 engages the pin 54, upward swinging movement ofthe arm 35 will be effected.

The hub of the segment gear 49 is extended inwardly as indicated in Fig.5 and at its inner end it is provided with an arm 56. The free end ofthe arm 56 is bifurcated as clearly shown in Fig. 5 and a member 51 ispivoted in said bifurcations. The member 51 is provided with a tailpiece 58 having its end arranged to engage an adjustable stop screw 59carried by a lug formed integral with the arm 55. The member 51 is thuspermitted to swingin one direction on its pivotal connection with thearm 55, but-limited in swinging in the opposite direction by the stopscrew 59. The purpose of this construction will appear in thedescription of the operation of the mechanism hereinafter given.

For receiving full spools, there are provided tracks such as indicatedat 65, these tracks being in vertical alignment with the tracks 29 andthe brake shoe and slidable through the free end of the bracket 5|.

For initially receiving a spool from the arm 35 after paper is wound onthe spool and for conveying the full spool to the tracks 50, track ex- 5tensions 55 are provided. The track extensions 55 are preferably ofhumped formation as best shown in Figs. 2 and 3 and these extensions maybe supported by suitable connections to the tracks 50 and to therespective frame memhere 24.

For facilitating the automatic transfer of the paper web from a fullspool to an empty spool, air showers are provided. One such shower isindicated at 56 and consists merely of a suitable pipe provided with airjets 51, the pipe being supported in suitable brackets 53 carried by theframe members 30. Another air shower is indicated at 69 and consists ofa similar pipe carried by arms such as I0 which extend upwardly from thelinks 52. The source of compressed air for the shower pipes 66 and 59may be any convenient source and in this instance the respective showerpipes may be connected to the air supply for the pneumatic cylinder 40.

In Fig. 6, the control of air supply for the pneumatic cylinder is shownas including a pair of electrically operated valves II and 12. The valve'H is of a more or less standard type of solenoid controlled valve soarranged that when the current is turned on the valve II will be openedso as to permit compressed air to enter the left hand end of thecylinder. The valve 12 which is a similar but inverted type of solenoidcontrolled valve is so arranged that when the current is on, the righthand end of the cylinder is opened to the atmosphere to relieve orexhaust the air from the portion of the cylinder. to the right of thepiston. The valves H and 12 are furthermore so arranged that when thecurrent is off, the valve II will open the left hand end of the cylinderto the atmosphere and the valve 12 will admit compressed air to theright hand end.

The electrical control of the valves H and I2 may be arranged for manualoperation but it is preferably arranged so as to be both manually andautomatically operable.

One switch for controlling the valves II and 12 is designated A, thisswitch being suitably mounted adjacent the end of the track extension asclearly shown in Fig. 3. The switch A is a normally closed switch and isadapted to be opened by engagement of a portion of the spool shaft withthe switch lever II. The switch A is so ar- 5 ranged that when an emptyspool is delivered to operative position relative to the drum It, theswitch A is opened to break the circuit controlling the valves H and 12.The arrangement is also such that the switch A is held open by the emptyspool shaft until such time as the roll of paper on the spool shaft hasreached such a side that the roll will be transferred from the end ofthe arm 35 to the track 55. When such transfer switch B is illustratedin Figs. 1 and 5. By

reference to the said figures, it will be seen that rotate onerevolution to any number between approximately 220 and 650 revolutionsof the shaft 16. Depending upon the setting of the variable speed unitM, the shaft may be caused to rotate one revolution for any length of'paper between approximately 2,000 and 6,000 feet. The high speed shaftit of the variable speed unit is provided with a large sprocket wheel 11which is connected by means of a suitable chain indicated at 78 to avery small sprocket wheel 19 carried by the free end of the shaft of thedrum l0.

The slow speed shaft lb of the variable speed unit it is connected to ashaft 80 through the agency of a suitable magnetic or other clutch 8i sothat the connection between the shaft 80 and shaft may be broken topermit manual adjustment of the shaft 80 and parts carried thereby.- Theshaft 00 is rotatably mounted in suitable bearing members 02 and 83.which are supported on a base 86. A spring pressed drag element at isarranged to bear on the shaft d0 to prevent too free rotation thereof.

As clearly shown in Fig. 5, the switch B is mounted on the base at andit is controlled by a cam roller 06 mounted on a disc M which is in turnsecured to the shaft 80. The arrangement is such that when the disc 3?has made one complete revolution, the cam roller 8t will engage the freeend of the switch arm st to throw the switch. The switch B is also anormally closed switch, which is opened and, therefore, breaks the electric circuit controlling the valves ii and 52 when the measured ount ofpaper has been wound on the spool.

The operation of the mechanism may be described as follows. I

As shown in Fig. 3, a roll of paper has been built up to include thedesired number of feet and it may be assumed that the measuringapparatus, best shown-in Fig. 5, will now actuate the switch B to openthe circuit controlling the valves ii and it. When the electric circuitis thus broken, the valves ii and it will be so adjusted that compressedair will be delivered into the right hand end of the pneumatic cylinder50 to thereby move the rack bar 03 to the left. Such movement of therack bar, transmitted through the gears 0t and segments tit, causes thearm 69 and part bl to swing in a counter-clockwise direction so that thepart 51 engages the spool shaft and propels the full roll upwardly overthe humps of thetrack extensions 65, whereupon the full roll rolls downthe inclined portions of said extensions and comes to rest as anincident to engagement of the brake shoes fit on the brake Duringtheinitial portion of the counter-clockwise movement of the arms 5%, thelinks 52 are pulled upwardly, but because of the pin and slot connectionwith the arm 55, no movement is tmitted to the arm 36. During the timeof the lost motionbetween the link 52 and arm 55, the full roll of paperis being moved away from operative position-relative to the drum l0 soas to permit anempty spool .to be delivered to such position. When thelower end of the slot 53 engages'the pin 54, continued upward movementof the link 52 will of course causethe arm 36 to be swung in a clockwisedirection so as to theref by carry an empty spool S into paper-receivingposition, as illustrated in Fig. 2. 5

By reference to Fig. 2, it will be seen that the paper-web will thenextend over and around the empty spool S and through a loop formationdesignated L, and thence to the full roll P It will be understood thatthe loop L will be formed be- 10 cause of the fact that the paper web Pis continuously fed to the drum it! while the rotation of the full rollP is stopped by the described brake arrangement. The air showers 60 and09 assist in forming the loop L by blowing the paper web 15 in theproper direction. The lower shower 6? also serves to direct the paperloop into engagement with the web of paper coming upon the drum l0 sothat the loop is thereby carried into the nip between the empty spool Sand the drum 20 to thereby attach the paper web to the empty spool. Whenthe paper web is' of a thin and light character such as a flimsy crepeor tissue paper, the portion of the web between the empty spool and thefull roll will be'readily broken so as to as separate the web from thefull roll and to permit continued winding of the web on the empty spool.In the case of heavier paper, various well known arrangements forsevering or breaking the web may be utilized. mechanism is illustratedas arranged for handling thin crepe paper which maybe readily broken andhence no severing mechanism is illustrated.

Various other arrangements for directing the web of paper into windingengagement with the 35 empty spool S may obviously be used instead ofthe air showers described and, in fact, the mechanism has beensuccessfully operated without any air shower or similar mechanism. Theair for the showers t6 and 6.9 may be controlled by the 40 valves ii andit or itmay be independently controlled as desired.

When an empty spool S is raised to the operative position illustrated inFig. 2, the switch A is opened. Inasmuch as the switch B is already 4open, the opening of the switch A has no immediate efi'ect on theelectric circuit or on the valves ill and i2. l-Iowever, the disc ti iscontinuously driven by reason of its connection to the drum and hencethe cam roller 8% will soon release the switch arm 00 and permit thesame to again close the circuit. Hence when the switch B closes thecircuit, the circuit nevertheless remains broken by the switch A untilsuch time as the empty spool is filled to such a point that it istransferred from 55 the arm 36 to the track extension 65. When suchtransfer takes place, the switch A will again be closed, whereupon thecircuit is again completed and the valves ii and it so adjusted that theair pressure is turned to the left end of the cylinder W to therebycause the rack it to move outwardly or to the right, with the resultthat the arm 36 is again lowered to the position illustrated in Fig. 3.The arm 56 is also returned from its advanced position as shown in Fig.2,'to its starting position as shown in Fig. 3. In such rearwardmovement of the arm 50, the back edge of the end members 01 engage thespool shaft and swing on their respective pivots so as to pass the spoolshaft without pressing the partially completed roll of paper against thedrum it] When the part "i clears the spool, a suitable springarrangement associated with the pivot pin or otherwise (not shown)serves to restore the part to its operative position as shown in Fig. 3.it

In the present instance, the 30 By reference to the wiring diagram shownin Fig. 4, it will be noted that switches C and D are also incorporatedin the electric circuit. The switch C is a normally closed switch and isprovided for the purpose of permitting manual control in place of thepaper-measuring switch B so that the winding of the paper web on oneroll may be terminated at any desired time and a new roll started. Theswitch D is a normally open switch and is so arranged that by closingthe circuit therewith, the arms 36 may be lowered independently of theaction of the spool on the switch A. In other words, while a spool is inoperative position holding the switch A open, the switch D may bemanually closed to cause the arms 38 to be lowered.

By the described arrangement of automatic switches and electricallycontrolled valves H and 12, the operation of the paper reeling mechanismmay be completely automatic. It being only necessary for an attendant tosupply the apparatus with empty spools and to release the full rollsfrom the brake devices.
